Summary

My first attempt at 3D designs, following a full size BB8 build I thought I'd tackle R2D2. Here's a full size Dome (Work in progress). The lower and upper rings have holes for alignment which 1.75 filament can be used in on the edge to edge gaps. Top pie pieces have removable supports. All is designed for ABS to minimise shrinkage and warping.

Notes:

Generally most pieces are designed to use need minimum or no support. Recommend at least 3 layers (or 4) to allow for sanding to a smooth finish.
